## Overview

The STEPPERONLINE High Torque Nema 23 CNC Stepper Motor delivers an impressive 3Nm (425oz.in) holding torque with a precise 1.8° step angle, powered by a robust 4.2A rated current. Its compact 57x57mm frame and 114mm length make it ideal for CNC mills, lathes, and routers requiring reliable, high-performance motion control. Built with durable alloy steel and designed for bipolar 4-wire operation, this motor is engineered for professionals demanding precision and power in their automation projects.

## Description

This is the strongest model for Nema 23 stepper motor, it with 1.8 deg. step angle (200 steps/revolution). Each phase draws 4.2A, allowing for a holding torque of 3.0Nm(425oz.in). Electrical Specification: * Manufacturer Part Number: 23HS45-4204S * Motor Type: Bipolar Stepper * Step Angle: 1.8 deg. * Holding Torque: 3.0Nm(425oz.in) * Rated Current/phase: 4.2A * Phase Resistance: 0.9ohms * Inductance: 3.8mH+/-20%(1KHz) Physical Specification: * Frame Size: 57 x 57mm * Body Length: 113mm * Shaft Diameter: 10mm * Shaft Length: 24mm * D-cut Length: 20mm * Number of Leads: 4 * Lead Length: 400mm * Weight: 1.8kg Connection: Black(A+), Green(A-), Red(B+), Blue(B-) Warning: Make sure the motor connect to a constant current or chopper drive controller before you test motor. Connecting the motor directly to a power supply will destroy the motor.

Review: Moteur costaud, câbles bien assez longs. C'est du classique et il fait parfaitement son travail.
Review: used these for a rail system and an arduino build that required a good 50lbs of lift across two motors. These don't disappoint. They can heat up, so I set the stay current to 50% and they still hold steady but stay cool. Good motor.

## Questions & Answers

**Q: Is there an adapter available to fit the 11mm input shaft of a 20:1 speed reducer nmrv030?**
A: They are researching it here, where the motor is sold. Wish I had an answer, but at least I'm not THAT guy.

**Q: How many RPMs will the motor run before the torque drops in half?**
A: The torque is highest at a slow 10 RPM. The torque drops linearly at the RPM increase. It starts to skip pulses because of low torque at about 200 RPM. I had to add a 100 tooth to 36 tooth xml timing pulleys to increase the torque.

**Q: Where can I get a gear that works with this 10mm shaft? Most of those I've seen are in standard, not metric units.**
A: I've had luck finding pulleys on EBay. I'm not sure about gears but it would be worth a shot if you haven't already looked. Also you could buy something to fit on a 3/8in shaft and drill it out to 10mm.

**Q: What is the maximum power output in Watts? I’m sure it’s higher than the 3W they have listed.**
A: Hello, 

The power is calculated as:
P = V *I* # of coils active, or equivalently 
P = I^2*R* # of coils active
For instance, if only one coil is active,
P=4.2^2*0.9*1 = 15.87 watts
If two coils are active, such as when the motor is holding a position, then the power doubles, which comes down to 31.75 watts. 

Hope this helps,

Hector
